Here are some things toy can check and try.


Connection faults
--


Check the speaker cables for shorts or damage. Crossing speaker wires can destroy receivers.

Some units are sensitive to speaker polarity problems. Make sure both sets of speaker cables have the correct polarity.

Very thick, or otherwise incorrect speaker cables can also cause faults like this. Try thinner wire if you are using very thick wires.

You may have the wrong speakers. Check the resistance the unit expects (usually 4 or 8 ohms), and make sure it matches. Try different speakers.

Could be other speaker faults. Some active speakers can develop faults, or there may be an internal fault in the speakers. Try different speakers.






Thermal overload:
--

As a general rule, don't run the second set of speakers if you don't need them - usually runningthem will degrade audio quality, increase power consumption, and increase the liklihood of thermal overload.

Try listening on a lower volume, see if it still does it. I have a unit that behaves this way mostly in summer when it is warm. If it does not do it when the volume is low, that's an indicator it may be thermal overload.

Check clearances. Don't block vents or place the unit in an enclosed space. Check the manual for a guide.

Check for dust, you might need to open it, (This will void the warranty if any, and can be dangerous even if the power is disconnected). You may use an air blower (like in a can) to clear the dust - or carefully use a vacuum cleaner).

If you suspect thermal overload, try pointing a domestic fan at the unit and see if it still does it.



Internal fault
--
Sometimes faults in the unit can cause these sort of symptoms. I've seem problems with volume knobs, and other parts. You'll need a proper service agent to investigate if this is suspected.

How do i check to see what is causing my receiver to shut off


The amp protection circuit has been activated. Remove the power cord from the wall outlet immediately. Disconnect all speaker cables and input sources, and leave the AV receiver with its power cord disconnected for 1 hour. After that, reconnect the power cord and reconnect an input and a pair of speaker wires onto the unit. If the receiver still does not turn on than you will have to bring it in for service. Turn up the volume and if the receiver doesn't shut down, power off the receiver and add another pair of speakers. Power up the unit again and turn up the volume. If it doesn't shut down, power off the unit again. Now connect all your input sources and turn on your receiver. If the unit shuts down again, your unit will need to be further serviced at an authorized Onkyo service center.

I have a yamaha, natural Sound Av receiver RX-V483, every time that i start the unit it will shut down after 5 seconds. thank you very much


It indicates an output load problem, dis-connect the speaker wires from the back of receiver. Next power on and turn the volume right down, if the unit runs, check for shorts in the speaker wires and speakers. But if it still shuts down "with speakers and wires dis-connected" one or more of the audio output ic's is shorted and will need a professional to assess the item.

I set the levels for all the speakers where I want them to be set at. But when I turn the unit off I lose all the speaker level settings and have to reset them


Some recievers have both a "power switch" and a "stand by" switch. Here is the difference.
"Power switch" eliminates all power input and most likely the memory in the unit too just like your stating in your situation.
"Stand by" switch shuts down all major components but keeps a small ammount of power to the unit to conserve any stored settings

Receiver shuts off at higher volumes


The receiver may be too under powered for your speakers or the speaker ohm's may not be matched for your amp.

The reason it is shutting off is likely because the amp is becoming overloaded. At lower volumes the amp can handle the load of the speakers, but at higher volumes the power supply of the amp can't keep up with the power demand the speakers are pulling.

If you were previously able to turn the reciever high without turning off, then there is likley something wrong with the amp or possibly a blown speaker.

Try measuring the resistance of the speakers if you have access to a multimeter. They should normally read 8 ohms for home speakers, but some common home speaker impedances in order from (I'm assuming) most common to least common are are 8, 4, 2(bose), and sometimes 10 or 12 ohms. The lower the number of ohms, the more power the amp will need to put to the speakers and the more chance you could be overloading your amp.

When i shut off the unit it displays 2nd zone on


For some reason your multizone operation is enabled. A quick browse through your manual should help you turn Zone 2 off. Multizone is used if you have speakers or amplifiers in other rooms and you want to control them with one source.

HI,have modle vm19311ts,,,,need to know what wires to hook to power to test,,,was a 2nd hand unit for sale,,,thank,s for any help


You'll want to power the red (switched ignition - the one that turns the system off when the key is off) and the yellow (constant 12V - used to maintain memory settings and tone settings when the car is off). Ground the black wire. This will allow you to power up the unit, although with no speakers hooked up you won't hear whether the internal amplifier works.

Yamaha rxv-992 receiver wont power up


Disconnect all your speakers from the receiver. Turn the power on, and see if it stays on. If the unit shuts off with all the speakers disconnected, then you most likely have a faulty unit, and it will need to be repaired or replaced.

If the unit stays on with all the speakers disconnected, then you most likely have a bad speaker or a bad connection with the speaker wire.

Starting with one speaker, hook it up, and turn the unit on, and again see if the unit stays on, or if it shuts off. Do this until the unit shuts off when you connect a speaker.

Then disconnect all the other speakers, and leave the suspect speaker attached. Again, try to power up the unit. If it fails with that speaker attached, but works when it is not attached, then that speaker is your problem.

Power problem?


???

1. Is the head unit powering the speakers directly or through an amp?
2. What ohm load (4,8,) per channel and how many speakers?
3. Does it do it with the bass set all the way down?

If you have access to a voltmeter see what the voltage is on the yellow and black wires when it is diming. It should be stable ~ 13.5v with car on. if its < 10v when dimming either there is:

1. Shorted speaker lead.
2. Bad ground to radio.
3. loose power feed to radio.
4. Ohm load below 4 ohms, causing the eccess current draw.

Shutting down


Try first to disconnect all your speakers and see if the sdame thing happens. if it dosent, turn off and start to connect up one speaker at a time. BUT always turn off unit while connecting speakers. Keep connecting till you get to the one that makes the system shut down. Then check the wires for splices cuts or shorts and make sure the ends where they connect to the speaker and reciver isent shorted. if it doesnt work with all the speakers disconnected theres a short in the unit and if its new take it back. Good Luck
